except 90% of writers in hollywood nowadays are dogshit so you end up with shit like Fantastic Beasts (scripts all written by JKR) when you try to do new original stuff. Sure, if you get VInce Gilligan or Tony Gilroy to make the show you'll get 10/10 everything but those kind of people aren't interested in this sorta bullshit, you get the usual retards who write take established good IPs like Rings of Power, Resident Evil, Cowboy Bebop, Foundation, Witcher and turn it all into dogshit
so yeah, if I was WB i'd stick carefully to source material everyone loves rather than trying something new, because that has failed miserably almost every time for them in the last few years.
Chris Columbo (director of the first few movies) also apparently wants to make a movie of The Cursed Child play which takes places like 20 (?) years after Deathly Hallows and I'd assume brings back most of the OG cast.
